SPARK ARRESTER AND CONSUMER.

SPECIFICATION forming part of Letters Patent No. 241,186, dated May 10, 1881.

Application filed March 14, 1881. (No model.)

To all whom it may concern:

Be it known that l, ALFRED BERNEY, a citi- 'zen of the United States, residing at the city of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Spark and Gas Consumers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to that class of spark arresters and consumers in which the sparks, 850., are returned to the furnace, there to be consumed and assist in the combustion of the fuel and generation of steam; and the invention consists in the construction and arrangement of parts, as will be more fully described hereinafter, reference beinghad to the accompanying drawings and the letters of reference marked thereon.

In the drawings, Figure 1 is a longitudinal section of a locomotive-boiler embodying my invention. Fig. 2 is a vertical cross-section of a modification of the stack and smoke-arch. Figs. 3 and 4 are detail views of the inverted cone.

In the drawings, A represents the furnace of a locomotive-boiler, and B are the tubes connecting with the smoke-arch, over which the stack L is secured to the saddle K. In the smoke-arch are arranged the usual exhausttips Dand lift or blast pipe E, and to said exhaust-tips is secured a wire-netting or sheetmetal perforated tapering pipe, I, extending to the top of the chimney. In the said chimney is arranged the inner barrel, M, which forms an annular space, m, connecting with the saddle and the pipe F, that forms a continuous passage, with the return-fines (J, to the furnace, and through said passage the sparks, cinders, &c., are returned to the tire, and are there entirely consumed and assist in the generation of steam. A steam-pipe, G, provided with a stop-cock, H, enters the connecting-pipe F, and assists in forcing the sparks, cinders, &c., back into the furnace.

As a modification of the wire-netting extending to the top of the stuck, I sometimes employ a hollow perforated inverted cone, 1, having at its upper end a flange, 0, by which it is held in position between the flanges 0 of the stack, as shown in Fig. 2. The object of this wire-netting or inverted cone is to prevent an y sparks or cindcrs from passing out of the stack, and yet'to allow the smoke and exhauststeam to escape, as in someinstances said smoke would have a tendency to dampen or even extinguish iheJire, especially in wood and certain kinds of coal, and it also prevents backpressure on the eyliiuler-pistons. The sparks are also pulverized, as they are thrown against the wire-nettingorinvcrted cone over and over again by the action of the exhaust-blast, until they become so line that they are merely dust and can do no harm or are not of much use.

The perforations in the cone may be made round, elongated, or any other suitable shape, and the cone or netting can be easily removed and replaced by a new one when worn out.

The annular space between the inner barrel and the netting or cone becomes highly heated, and the air passing into it becomes very hot before it is forced or drawn down the annular space between the inner and outer barrels of the stack, and thence into the furnace with the sparks, steam, &c.

I am aware that a wire-netting extending from the exhaust-tips to the top of the chimney, and also inverted perforated cone, have been used in connection with sparkarresters, but not in combination with devices such as I have shown in my spark arrester and consumer, and I do not therefore broadly claim such; but,

Having thus described my invention, what I claim, and desire to secure by Letters Patent, lS-- 1. In a spark arrester and consumer, the combination of a wire-nettin g, l, or its equivalent, as described, which prevents the egress of sparks from the stack, with the annular space m, saddle K, connecting-pipes F, and returnflues 0, all arranged substantially as specified.

2. In a spark arrester and consumer, the combination of a wire-netting or inverted perforated cone with the annular spaces formed between the inner and outer barrels of the stack and the netting, the saddle K, e0nnect- I 4. In a spark-arrester, the combination of ing-pipes F, and return-fines 0, all arranged the saddle K, provided with inclined guides, substantially as shown, and for the purpose steamjet G, return-pipe F, and tube 0, all arherein described. ran ged and for the purpose specified.
